Toxoplasmosis is a major public health concern in many countries of the world. A cross-sectional and follow up experimental study designs were used for seroepidemiological bioassay studies, respectively from November 2012 to April 2013. The objectives estimate seroprevalence T. gondii infection, assess risk factors isolate parasite camels Fentale district, Ethiopia. direct agglutination test (DAT) indirect enzyme linked immunosorbent assay (ELISA) kits camel sera. Hearts tongues (each 25 g)...

We performed a seroepidemiological study of Toxoplasma gondii infection in free-range chickens from October 2012 to May 2013. used cross-sectional two-stage cluster sampling collect blood samples wing veins 601 central Ethiopia. T. gondii-specific antibodies were assayed by modified agglutination test (MAT). collected information about risk factors questionnaire and univariable multivariable logistic regression assess factors. An overall seroprevalence 30·5% [95% confidence interval (CI)...

The teaching of veterinary anatomy was started in line with the establishment first school Lyon 1762. During this time fewer tools and techniques were available for displaying visualization organs order to teach anatomy. Over years, many methods, tools, that are essential students anatomists developed. Teaching materials like cadaver which preserved by formalin has being using a long time. Instead cadavers, various have also been different parts world. These alternative not hopeful meet...

This study aimed to develop a protocol for the thin section plastination of kidney with local polyester resin and examine anatomical details this specimen. The sample was fixed 10% formalin fixation solution then sectioned into 3 mm slices. four stages technique were used. Firstly, samples kept in 99.5% acetone baths at -25ºC dehydration. After process, sections placed impregnation process started room temperature (20ºC) under vacuum. Following forced impregnation, curing chambers...
